I'm going to php|tek, too, and i'll have two more talks there.
This is going to be sort of a stunt as the MySQL user conference and php|tek overlap, so i'll have to jump on a plane right after the MySQL conference is over to cross the USA. I also won't be able to attend any php|tek sessions myself as the last conference day only has two session time slots 
My first talk will be on PHP and MySQL Cluster and after that i'll talk about PHP and WebDAV.
